使用volley框架遇到空指针，求大神

Question

JsonObjectRequest jsonRequest = new JsonObjectRequest(
Request.Method.POST, url, json,
new Listener() {

                                @Override
                                public void onResponse(JSONObject response) {
                                    // TODO Auto-generated method stub

                                }
                            }, new Response.ErrorListener() {

                                @Override
                                public void onErrorResponse(
                                        VolleyError error) {
                                    // TODO Auto-generated method stub

                                }
                            });

提示为

上面最后加黑的RegistActivity.java:74指的就是上面的代码。。。上面的参数都初始化了。

肯定你你传的对象有问题，调试一下，没准你传递的就是空值
